ABSTRACT:
An apparatus for metering and singulating electronic devices such as integrated circuits that are arrayed initially in a column. A support member positioned over one end of the column has a plurality of spaced apart coil springs that extend radially to engage a leading one of the devices. The support member rotates at a constant rate to carry one or more of the springs into engagement with the leading device, upon further rotation deflect the spring to store energy, and upon still further rotation, cause the spring or springs to snap back to their initial radial orientation thereby accelerating the leading device to separate it from the column.
